Macbook optimizer

Security checks for vulnerabilities and agentic risk

Overview

This MacBook optimization skill is locally focused and purpose-aligned, but users should review any cleanup or process changes before approving them.

Install only if you want an agent to inspect local Mac performance and storage. Treat cleanup, duplicate removal, process termination, startup changes, and cron-based monitoring as actions that should show a preview and wait for your explicit approval.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Missing User Warnings

Finding

The README advertises 'Cleanup Tools' that find large files and suggest cleanup, but provides no warning that cleanup actions may affect user data or system stability if acted on carelessly. In an agent skill context, users may reasonably infer the skill can recommend or initiate deletion-related actions, so missing safety guidance increases the risk of accidental destructive behavior.

Missing User Warnings

Confidence
93% confidence
Finding

The usage example 'Clean up disk space' encourages a potentially destructive operation without warning that cleanup may be irreversible or remove important files. Because this is a Mac system-management skill, the context makes the omission more dangerous: users may trust the agent to make file-management decisions on their behalf.

Vague Triggers

Medium
Category

Confidence
93% confidence
Finding

The usage examples are broad, natural-language requests like 'fix any issues' and 'show me everything,' which can cause the skill to match common Mac support requests without clear user intent to invoke this specific skill. Because the skill includes automation such as cleanup, process management, GUI opening, and possible continuous monitoring, ambiguous activation increases the chance of unintended execution of impactful actions.

Vague Triggers

Category

Confidence

Finding

The phrase 'Show me my disk usage visually and clean up automatically' couples a common diagnostic request with automatic remediation, making it easy for an ordinary user request to trigger file-deleting or system-changing behavior. In this skill's context, that is more dangerous because the document explicitly advertises automated cleanup of caches, logs, temp files, downloads, and duplicates, so ambiguous activation could lead to unintended data loss or disruptive changes.
